Upgrade from TW Acustic Raven AC-3 to what?


I have had the TW turntable (with 10" Da Vinci Grandezza arm and Grandezza cartridge) for two years. I have been happy with this TT and can live with it for a long time although i wish it wasn't as dark sounding, that the soundstage could be more spacious and the bass tighter. The upgrade bug in me is wondering for 50K ore thereabout, is there a TT that is superlative over the TW? One that would end my upgrading itch for the next 10 years?

Knotless thead drive not difficult if you know what you are doing. Sorry about the pun.

I used Japanese embroidery silk which worked quite well by thread drive standards but is so far behind the state of the art that I dropped it as a commercial proposition. The fun part was that a huge range of colours is available - I used red, green and yellow and called it natty thread (with apologies to the late Bob Marley).
Dear Mosin,
Actually i have not sold my TW/Grandezza. Trying to tweak it in the mean time.
Simultaneoulsy, I have learnt a lot from the postings which i appreciate very much.

Alec,

My best wishes that you get it exactly like you want. That is one of the fun parts of our hobby, and you'll know when it is there. After all, what we do is about music, isn't it?

Regards,
Win
Alectioning, what I learned from a friend in France: it is not easy to sell a Raven at the moment. I do not why but many potential buyers my friend contacted were quickly offered nearly new Ravens for a very good price. I have no clue how this could work.
Alectiong, Try all the tweaks first then think about getting a Koetsu Coralstone Stereo cartridge and a Koetsu Coralstone Mono cartridge, two Graham Phantom II arms or one arm with two wands and mount your TW...AC-3 on a Minus-K. This is the path I'm thinking about for my TW...AC-3. If this and your tweaks don't work you might think about the mounting your arms and cartridges on a TW Black Knight. Failing that, going another route like the Continuum Caliburn, Cobra and Castellon might be satisfing. Let us know how things go.
